Subject: Re: [USRP-users] Error in RFNoC grc with OOT module
Hello Jose,
this might be an indentation problem at the XML that is located at
your_oot/grc/your_block.xml. Do you mind sharing with us that file?
Also, I remember seeing this error in earlier versions of the tool, so it would
be interesting to know if it still happens, and under what conditions. Could
you please tell us which is the last commit that you are pointing to at
"gr-ettus"? To check, please go to your gr-ettus repository and run:
$ git log
If it is not updated, it is always recommended to update.
Regards,
-N
